Instagram Slider Carousel appearing cut off

Site URL: https://cosmotemplate.squarespace.com/?password=pearler

Wondering why this Instagram slider carousel is appearing cut off on some devices? 

Try adding this to Design > Custom CSS > Then save & reload the site

@media screen and (max-width:767px) {
div#block-yui_3_17_2_1_1635302311229_9385 .sqs-gallery-design-strip .sqs-wrapper {
    width: 100% !important;
    left: 0 !important;
}
}

@tuanphan Thanks! I'm still having a little trouble with this as well as horizontal overflow:
